Class FrameAnnotatorAdapter

java.lang.Object
  net.sf.jaer.graphics.FrameAnnotatorAdapter

All Implemented Interfaces:

FrameAnnotater

public class FrameAnnotatorAdapter
extends java.lang.Object
implements FrameAnnotater

Provides empty implementations of all FrameAnnotater methods, in case a class wishes to subclass this class and simply override the desired annotation methods.

Constructor Summary

FrameAnnotatorAdapter()
Creates a new instance of FrameAnnotatorAdapter

Method Summary

void	annotate(float[][][] frame) annotate the RGB frame somehow by color pixels in the rendered pixel frame data.
void	annotate(javax.media.opengl.GLAutoDrawable drawable) Each annotator enters annotate with graphics context current, in coordinates with pixel 0,0 in LL corner (note opposite from Java2D) and pixel spacing 1 unit after the scaling transform (which is already active).
void	annotate(java.awt.Graphics2D g) each annotator is called by the relevant class (e.g.
boolean	isAnnotationEnabled()
void	setAnnotationEnabled(boolean yes)

Method Detail

annotate

public void annotate(java.awt.Graphics2D g)

Description copied from interface: FrameAnnotater

each annotator is called by the relevant class (e.g. EyeTracker) and enters annotate with graphics context current, in coordinates with pixel 0,0 in UL corner and pixel spacing 1 unit before scaling transform (which is already active).

Specified by:

annotate in interface FrameAnnotater

Parameters:

g - the Graphics2D context

annotate

public void annotate(javax.media.opengl.GLAutoDrawable drawable)

Description copied from interface: FrameAnnotater

Each annotator enters annotate with graphics context current, in coordinates with pixel 0,0 in LL corner (note opposite from Java2D) and pixel spacing 1 unit after the scaling transform (which is already active). The FrameAnnotater then can use JOGL calls to render to the screen by getting the GL context, e.g. the following code, used in the context of an AEChip object, draws a golden lines from LL to UR of the pixel array.

        GL gl = drawable.getGL();
        gl.glBegin(GL.GL_LINES);
        gl.glColor3f(.5f, .5f, 0);
        gl.glVertex2f(0, 0);
        gl.glVertex2f(getSizeX() - 1, getSizeY() - 1);
        gl.glEnd();

Parameters:

drawable - the OpenGL drawable components, e.g., GLCanvas

annotate

public void annotate(float[][][] frame)

Description copied from interface: FrameAnnotater
